Catfish Pond Mitigation Site
Baseline Monitoring Document and As-Built Baseline Report-FINAL i
EXECUTIVE SUMMARY
Wildlands Engineering, Inc. (Wildlands) implemented a full delivery project at the Catfish Pond
Mitigation Site (Site) for the North Carolina Department of Environmental Quality Division of Mitigation
Services (DMS). A total of 7,140 linear feet (LF) of perennial and intermittent streams were restored and
enhanced in Durham County, NC. The Site is expected to generate 3,748.800 stream mitigation units
(SMUs) when calculated along stream centerlines. The Site is located approximately 12 miles north of
the City of Durham and approximately 3 miles east of the Orange/Durham County border (Figure 1). It is
in the Neuse River Basin 8-Digit Hydrologic Unit Code (HUC) 03020201 and within a DMS targeted
watershed for the Neuse River Basin Hydrologic Unit Code (HUC) 03020201020040 and NC Division of
Water Resources (DWR) Subbasin 03-04-01. The Site contains Catfish Creek and 3 unnamed tributaries.
The streams drain to Mountain Creek, which flows into Little River, the Eno River, and then Falls Lake.
Falls Lake is classified as Water Supply Waters (WS-IV) and Nutrient Sensitive Waters (NSW). The 20.73-
acre Site is protected with a permanent conservation easement.
The Site is located within the Targeted Local Watershed (TLW) as discussed in the 2010 Neuse River
Basin Restoration Priorities (RBRP), which highlights the importance of riparian buffers for stream
restoration projects (Breeding, 2010). Current and past degradation at the Site includes an in-line pond,
extensive logging, farm road crossings, stream channelization, and livestock access to streams and
buffers.
The project goals established in the Mitigation Plan (Wildlands, 2019) were completed with careful
consideration of goals and objectives described in the Neuse River RBRP plan. The project goals
established include:
•Exclude cattle from project streams;
•Reconnect channels with floodplains and riparian wetlands to allow a natural flooding regime;
•Improve the stability of stream channels;
•Improve instream habitat;
•Restore and enhance native floodplain and streambank vegetation; and
•Permanently protect the Site from harmful uses.
The project will contribute to achieving goals for the watershed discussed in the Neuse River RBRP and
provide ecological benefits within the Neuse River Basin. While benefits such as habitat improvement
and geomorphic stability are limited to the Site, others, such as reduced pollutant and sediment loading,
have farther reaching effects.
Site construction and planting were completed in March and April 2020. As-built surveys were
conducted in April 2020. The Site has been built as designed, with a few exceptions due to field
conditions, and is expected to meet the upcoming monitoring year’s performance criteria. Adjustments
were made during construction and specific changes are detailed in Section 5.1. Baseline (MY0) profiles
and cross-section dimensions closely match the design parameters, except where channel alignments
were adjusted due to bedrock in a section of Catfish Creek Reach 6 and UT1 Reach 3. Cross-section
widths and pool depths occasionally deviate from the design parameters but fall within a normal range
of variability for natural streams.

Section 1: PROJECT GOALS, BACKGROUND, AND ATTRIBUTES
1.1 Project Location and Setting
The Catfish Pond Mitigation Site (Site) is located in Durham County approximately 12 miles north of the
City of Durham and approximately 3 miles east of the Orange/Durham County border (Figure 1). From
Raleigh, NC, take I-40 West towards Durham. Take exit 279B for NC-147 N towards Durham/Downtown.
Travel approximately 8 miles and exit onto Duke Street. Merge onto South Duke Street and continue 4.3
miles until South Duke Street merges with US-501 N/N Roxboro Street. Travel north on US-501 N/N
Roxboro Street for 7.5 miles. Make a U-turn and travel south on N Roxboro Street for 0.2 miles, turn
right on the first gravel road. Drive approximately 0.2 miles and take the first right onto another gravel
road. The Site is located at the end of the gravel road. A conservation easement was recorded on 20.73
acres.
The Site is located within the Falls Lake Water Supply Watershed, which is within the Neuse River Basin.
Both the Neuse River and Falls Lake have been designated as Nutrient Sensitive Water (NSW). The Site is
within Hydrologic Unit Code (HUC) 03020201020040 and is located within the Neuse River Targeted
Local Watershed (TLW) (Figure 1) as identified in the 2010 Neuse River Basin Restoration Priorities
(RBRP) (Breeding, 2010). This document highlights the importance of riparian buffers for stream
restoration projects. Riparian buffers immobilize and retain nutrients and suspended sediment. The
RBRP also supports the Falls Lake watershed plan. Falls Lake is the receiving water supply water body
downstream of the Site and is classified as WS-IV and NSW.
The Site is located in the Carolina Slate Belt of the Piedmont Physiographic Province. The Piedmont
Province is characterized by gently rolling, well rounded hills with long low ridges and elevations ranging
from 300-1500 feet above sea level. The Site topography and relief are typical for the region. The
Carolina Slate Belt consists of heated and deformed volcanic and sedimentary rocks. The area is called
“Slate Belt” because of the slaty cleavage of many of the surficial rocks. The region’s geology also
includes coarse-grained intrusive granites.
Prior to construction activities, one of the primary causes of degradation on the Site was the creation of
an in-line pond on Catfish Creek Reach 6 sometime between 1940 and 1955. In that time period
extensive logging and farm road construction also took place at the Site. Aerial photographs from 1972
suggest that portions of UT1 had been straightened for agricultural purposes. Catfish Creek above and
below the pond, UT2, and Mountain Tributary showed few signs of channel manipulation. Table 4 in
Appendix 1 and Tables 7a-b in Appendix 4 present additional information on pre-restoration conditions.
1.2 Project Goals and Objectives
The project is intended to provide numerous ecological benefits within the Neuse River Basin. While
benefits such as habitat improvement and geomorphic stability are limited to the Site, others, such as
reduced pollutant and sediment loading, have farther reaching effects. Expected improvements to water
quality and ecological processes are outlined below as mitigation goals and objectives in Table 1. These
goals were established and completed with careful consideration of goals and objectives described in
the RBRP and to meet the DMS mitigation needs while maximizing the ecological and water quality uplift
within the watershed.

1.3 Project Structure, Restoration Type, and Approach
The Mitigation Plan was approved in July 2019. Construction activities were completed by Main Stream
Earthwork, Inc. in March 2020. Kee Mapping and Surveying completed the baseline as-built survey and
Bruton Natural Systems, Inc. completed planting in April 2020. Refer to Appendix 1 for detailed project
activity, history, contact information, and watershed/Site background information.

1.3.1 Project Structure
The project will provide 3,748.800 stream mitigation units (SMUs). Changes in stream alignment on
Catfish Creek Reach 6 due to bedrock in the floodplain reduced overall reach length by 10 lf. Refer to
Figure 2, the Project Component/Asset Map for the stream restoration feature exhibits, and Table 1 in
Appendix 1 for the project component and mitigation credit information for the Site.
1.3.2 Restoration Type and Approach
The design streams were restored to the appropriate type based on the surrounding landscape,
climate, and natural vegetation communities but also with strong consideration to existing watershed
conditions. The project consists of the stream restoration and enhancement activities as described
below (Table 2) and illustrated in Figure 2.

The design approach for this Site employed a combination of analog and analytical approaches for
stream restoration. Reference reaches were identified to serve as an acceptable range for design
parameters. Channels were sized based on design discharge hydrologic analysis. Designs were then
verified and/or modified based on a sediment transport analysis. This approach has been used on many
successful Piedmont and Slate Belt restoration projects (e.g., Underwood, Foust, Holman Mill, Maney
Farm, and Agony Acres Mitigation Sites) and is appropriate for the goals and objectives for this Site.
The morphologic design parameters are shown in Appendix 4, Tables 7a and 7b for the restoration
reaches, and fall within the ranges specified for C4 and B4a streams (Rosgen, 1996). The specific values
for the design parameters were selected based on designer experience and judgment and were verified
with morphologic data form reference reach data sets.

Section 2: PERFORMANCE STANDARDS
The stream performance standards for the project will follow approved standards presented in the
Wilmington District Stream and Wetland Compensatory Mitigation Updated in October 2016 by the
North Carolina Interagency Review Team (NCIRT). Annual monitoring and semi-annual site visits by
qualified personnel will be conducted to assess the condition of the project. Specific performance
standard components are proposed for stream morphology, hydrology, and vegetation. Performance
standards will be evaluated throughout the seven-year post-construction monitoring.
2.1 Stream
2.1.1 Dimension
Riffle cross-sections on the restoration reaches should be stable and should show little change in
bankfull area, maximum depth ratio, and width-to-depth ratio. Per DMS guidance, bank height ratios
shall not exceed 1.2 and entrenchment ratios shall be at least 2.2 for restored C channels and no less
than 1.4 for B channels to be considered stable. All riffle cross-sections should fall within the parameters
defined for channels of the design stream type. If any changes do occur, these changes will be evaluated
to assess whether the stream channel is showing signs of instability. Indicators of instability include a
vertically incising thalweg or eroding channel banks. Changes in the channel that indicate a movement
toward stability or enhanced habitat include a decrease in the width-to-depth ratio in meandering
channels or an increase in pool depth. Remedial action would not be taken if channel changes indicate a
movement toward stability.
2.1.2 Pattern and Profile
Longitudinal profile surveys will not be conducted during the seven-year monitoring period unless other
indicators during the annual monitoring indicate a trend toward vertical and lateral instability. If a
longitudinal profile is deemed necessary, monitoring will follow standards as described in the NCIRT
Wilmington District Stream and Wetland Compensatory Mitigation Update (2016) and the 2003 USACE
and NCDWR Stream Mitigation Guidance for the necessary reaches. Visual assessments and photo
documentation should indicate that streams are remaining stable and do not indicate a trend toward
vertical or lateral instability. A longitudinal profile was conducted as part of the as-built survey to
provide a baseline for comparison should it become necessary to perform longitudinal profile surveys
later during monitoring and to insure accordance with design plans.
2.1.3 Substrate
Channel substrate materials will be sampled in the four restoration reaches (Catfish Creek Reach 4 and 6
and UT1 Reach 2 and 3) using the reach-wide pebble count method. Reaches should show maintenance
of coarser substrate in the riffles than in the pools. Riffle cross-section pebble counts were conducted
during as-built baseline monitoring and will not be conducted during annual monitoring unless
observations indicate a trend toward finer substrate and a comparison is needed.
2.1.4 Photo Documentation
Photographs should illustrate the Site’s vegetation and morphological stability on an annual basis. Cross-
section photos should demonstrate no excessive erosion or degradation of the banks. Longitudinal
photos should indicate the absence of persistent mid-channel bars or vertical incision. Grade control
structures should remain stable. Deposition of sediment on the bank side of vane arms is preferable.
Maintenance of scour pools on the channel side of vane arms is expected.

Catfish Pond Mitigation Site
Baseline Monitoring Document and As-Built Baseline Report-FINAL 2-2
2.1.5 Hydrology Documentation
The occurrence of bankfull events will be documented throughout the seven-year monitoring period.
Stream monitoring will continue until performance standards in the form of four bankfull events in
separate years have been documented.
2.2 Wetlands
Wildlands installed four groundwater wells at locations requested by the NCIRT in comments made on
June 26, 2019. One is along Catfish Creek Reach 4 and three are along UT1 Reach 2. Although there is no
pre-construction wetland data for comparison, the purpose of the data from these groundwater wells is
to assess potential impacts to existing wetland hydrology from the project. Results are not tied to
success criteria nor stream crediting. It is expected that the project will result in a net increase in
wetland quality.
2.3 Vegetation
Vegetative performance for riparian buffers associated with the stream restoration component of the
project (buffer widths 0 – 50 feet) will be in accordance with the Stream Mitigation Guidelines issued
October 2016 by the NCIRT. The success criteria are an interim survival rate of 320 planted stems per
acre at the end of monitoring year three (MY3), 260 stems per acre at the end of monitoring year 5
(MY5), and a final vegetation survival rate of 210 stems per acre at the end of monitoring year 7 (MY7).
Trees should also average 7 feet in height at MY5 and 10 feet in height at MY7. No one species shall
account for more than 50% of the required number of stems within any vegetation plot at the end of
MY7.
The extent of invasive species coverage will be monitored and treated as necessary throughout the
required monitoring period.
2.4 Visual Assessment
Visual assessments should support the specific performance standards for each metric as described
above.
2.5 Schedule and Reporting
Monitoring reports will be prepared in the fall of each year of monitoring and submitted to DMS. Based
on the DMS Annual Monitoring Report Template (June 2017), the monitoring reports will include the
following:
• Project background which includes project objectives, project structure, restoration type and
approach, location and setting, history and background;
• Monitoring Current Condition Plan View (CCPV) maps with major project elements noted such
as grade control structures, vegetation plots, permanent cross-sections, and crest gauges;
• Photographs showing views of the restored Site taken from fixed point stations;
• Assessment of the stability of the Site based on the cross-sections;
• Vegetative data as described above including the establishment of any undesirable plant
species;
• A description of damage by animals or vandalism; and
• Maintenance issues and recommended remediation measures will be detailed and documented.

Catfish Pond Mitigation Site
Baseline Monitoring Document and As-Built Baseline Report-FINAL 3-1
Section 3: MONITORING PLAN
Monitoring will consist of collecting morphological, hydrologic, and vegetative data to assess the project
performance based on the restoration goals and objectives on an annual basis until performance criteria
have been met. The performance of the project will be assessed using measurements of the stream
channel’s dimension, pattern, substrate composition, permanent photographs, surface water hydrology,
and vegetation. Any areas identified as high priority problems, such as streambank instability,
aggradation/degradation or lack of vegetation establishment will be evaluated on a case-by-case basis.
The problem areas will be visually noted, and remedial actions will be discussed with DMS staff to
determine a plan of action. A remedial action plan will be submitted if maintenance is required. The
monitoring period will extend seven years beyond completion of construction or until performance
criteria have been met.
3.1 Stream
Geomorphic assessments will follow guidelines outlined in the Stream Channel Reference Sites: An
Illustrated Guide to Field Techniques (Harrelson et al., 1994), methodologies utilized in the Rosgen
stream assessment and classification document (Rosgen, 1994 and 1996), and in the Stream
Restoration: A Natural Channel Design Handbook (Doll et al, 2003). Refer to Figure 3 in Appendix 2 and
Record Drawings in Appendix 5 for monitoring locations discussed below.
3.1.1 Dimension
A total of seven cross-sections were installed along the stream restoration reaches. Two cross-sections
were installed per 1,000 linear feet of stream restoration work. Each cross-section was permanently
marked with pins to establish its location. Cross-section surveys include points measured at all breaks in
slope; including top of bank, bankfull, edge of water, and thalweg to monitor any deviations in
dimension. If moderate bank erosion is observed along a stream reach during the monitoring period, a
series of bank pins will be installed in representative areas where erosion is occurring for reaches with a
bankfull width of greater than five feet. Bank pins will be installed in at least three locations (one in
upper third of the pool, one at the mid-point of the pool, and one in the lower third of the pool). If bank
pins are required, exposure will be documented during each bank assessment and bank pins will be re-
set flush with the bank. Cumulative measurements will be assessed annually to document the severity of
bank erosion. Annual cross-section surveys will be conducted in MY1, MY2, MY3, MY5, and MY7.
Photographs will be taken annually of the cross-sections looking upstream and downstream.
3.1.2 Pattern and Profile
Longitudinal profile surveys will not be conducted during the seven-year monitoring period unless other
indicators during the annual monitoring show a trend toward vertical and lateral instability. If a
longitudinal profile is deemed necessary, monitoring will follow standards as described in the NCIRT
Wilmington District Stream and Wetland Compensatory Mitigation Update (2016) and the 2003 USACE
and NCDWR Stream Mitigation Guidance for the necessary reaches. Stream pattern and profile will be
assessed visually as described below in section 3.4.
3.1.3 Substrate
A reach-wide pebble count will be performed in the four restoration reaches (Catfish Creek Reach 4 and
6 and UT1 Reach 2 and 3) during monitoring years 1, 2, 3, 5, and 7 for classification purposes and to
show that riffles remain coarser than pools. Riffle cross-section pebble counts were conducted during
as-built baseline monitoring only unless observations indicate a trend toward finer substrate and a
comparison is needed.

Catfish Pond Mitigation Site
Baseline Monitoring Document and As-Built Baseline Report-FINAL 3-2
3.1.4 Photo Documentation
A total of 20 permanent photograph reference points were established along the stream reaches after
construction. Permanent markers were established so that the same locations and view directions on
the Site are photographed each year. Longitudinal stream photographs will be taken looking upstream
and downstream once a year to visually document stability. Cross-sectional photos will be taken at each
permanent cross-section looking upstream and downstream. The photographer will make every effort
to consistently maintain the same area in each photo over time.
3.1.5 Hydrology Documentation
Two automated crest gauges were installed on Site. The crest gauges were installed in surveyed riffle
cross-sections on Catfish Creek Reach 6 and UT1 Reach 2 (cross-sections 3 and 6). Crest gauge data will
be downloaded quarterly to determine if a bankfull event has occurred.
3.2 Wetlands
Four groundwater monitoring wells equipped with pressure transducers were installed to assess
hydrology in wetland areas. Pressure transducers will record groundwater pressure at least twice daily.
Data from the wells will be downloaded at regular intervals and included in annual monitoring reports
for informational purposes only. Results are not tied to success criteria nor stream crediting. It is
expected that the project will result in a net increase in wetland quality. Groundwater well locations are
shown in Appendix 2 Figure 3.
3.3 Vegetation
Planted woody vegetation will be monitored in accordance with the guidelines and procedures
developed by the Carolina Vegetation Survey-EEP Level 2 Protocol (Lee et al., 2008) to monitor and
assess the planted woody vegetation. A total of eight standard 10-meter by 10-meter vegetation plots
and one 5-meter by 20-meter vegetation plot were established within the project easement area, seven
fixed and two random.
Vegetation plots were randomly established throughout the planted area within the conservation
easement boundaries and five feet from the top of stream banks. Fixed vegetation plot corners have
been marked and are recoverable either through field identification or with the use of a GPS unit.
Reference photographs were taken at the origin looking diagonally across the plot to the opposite
corner during the baseline monitoring in March and April 2020. Subsequent annual assessments
following the baseline survey will capture the same reference photograph locations. Planted woody
stems will be marked annually, as needed, based off a known origin so they can be found in subsequent
monitoring years.
A new center point will arbitrarily be chosen each year within the conservation easement planted areas
for the two random vegetation plots. Trees within a 100 square meter area will be measured and
assessed as described below.
Species composition, density, and survival rates will be evaluated on an annual basis by plot and for the
entire Site. Individual plot data will be provided and will include height, density, vigor, damage (if any),
and survival. Mortality will be determined from the difference between the baseline year’s living planted
stems and the current year’s living planted stems. Vegetation surveys will be conducted during
monitoring years 1, 2, 3, 5, and 7.
3.4 Visual Assessment
Visual assessments will be performed along all stream restoration and enhancement areas on a semi-
annual basis during the seven-year monitoring period. Problem areas will be noted such as channel

instability (i.e. lateral and/or vertical instability, in-stream structure failure/instability and/or piping, or
headcuts), vegetation health (i.e. low stem density, vegetation mortality, invasive species or
encroachment), beaver activity, or livestock access. Areas of concern will be mapped and accompanied
by a written description in the annual report. Problem areas will be re-evaluated during each
subsequent visual assessment. Should remedial actions be required, recommendations will be provided
in the annual monitoring report.

Section 4: MAINTENANCE AND CONTINGENCY PLAN
Wildlands will perform maintenance as needed at the Site. A physical inspection of the Site shall be
conducted a minimum of once per year throughout the post-construction monitoring period until
performance standards are met. These site inspections may identify components and features that
require routine maintenance. Routine maintenance should be expected most often in the first two years
following construction and may include one or more of the following components.
4.1 Stream
Stream problem areas will be mapped and included in the CCPV as part of the annual stream
assessment. Stream problems areas may include bank erosion, structure failure, beaver dams,
aggradation/degradation, etc. Routine channel maintenance and repair activities may include chinking
of in-stream structures to prevent piping, securing loose coir matting, and supplemental installations of
live stakes and other target vegetation along the channel. Areas where storm water runoff flows into the
channel may also require maintenance to prevent bank failures and head-cutting.
4.2 Vegetation
Vegetation shall be maintained to ensure the health and vigor of the targeted community. Vegetative
problem areas will be mapped and included in the CCPV as part of the annual vegetation assessment.
Vegetation problem areas may include planted vegetation not meeting performance criteria, persistent
invasive species, barren areas with little to no herbaceous cover, or grass suffocation/crowding of
planted stems. Routine vegetation maintenance and repair activities may include supplemental planting,
pruning, mulching, and fertilizing. Exotic invasive plant species shall be controlled by mechanical and/or
chemical methods. Any vegetation control requiring herbicide application will be performed in
accordance with NC Department of Agriculture (NCDA) rules and regulations.
4.3 Site Boundary
Site boundary issues will be mapped and included in the CCPV as part of the annual visual assessment.
Site boundaries shall be identified in the field to ensure clear distinction between the Site and adjacent
properties. Boundaries are marked with conservation easement signs attached to metal posts. Boundary
markers disturbed, damaged, or destroyed will be repaired and/or replaced on an as needed basis.

Section 5: AS-BUILT CONDITION (BASELINE)
The Site construction was completed in March 2020 and as-built surveys were completed in April 2020.
The survey included developing an as-built topographic surface; as well as surveying the as-built channel
centerlines, top of banks, structures, and cross-sections. For comparison purposes, baseline monitoring
divided the reach assessments in the same way they were established for design parameters: Catfish
Creek Reaches 1-7, UT1 Reaches 1-4, UT2, and Mountain Tributary.
5.1 As-Built/Record Drawings
A sealed half-size set of record drawings are in Appendix 5 which includes the post-construction survey,
alignments, structures, and monitoring features. These include redlines for any significant field
adjustments made during construction that differ from the design plans. Where needed, adjustments
were made during construction based on field evaluation and are listed below.
5.1.1 Catfish Creek Reach 4
• Station 113+00 culvert installed based on dimensions listed in details of construction plan
sheets.
5.1.2 Catfish Creek Reach 6
• Station 118+30 log sill removed due to stability at head of riffle and stream banks during
construction;
• Station 119+76 rock sill removed due to bedrock in channel;
• Station 119+81 through 121+90 deviation of alignment due to bedrock in floodplain; and
• Station 122+54 reach break moved upstream from 122+71 due to bedrock in channel and to
minimize tree clearing during construction.
5.1.3 UT1 Reach 2
• No significant changes made.
5.1.4 UT1 Reach 3
• Station 217+10 riffle and rock sill not constructed due to bedrock in field; and
• Station 217+38 riffle and rock sill shifted upstream 10 LF due to bedrock in field.
5.2 Baseline Data Assessment
Baseline monitoring (MY0) was conducted between March and April 2020. The first annual monitoring
assessment (MY1) will be completed in late 2020. The streams will be monitored for a total of seven
years, with the final monitoring activities concluding in 2026. The close-out for the Site will be
conducted in 2027 given the performance criteria have been met.
5.2.1 Morphological State of the Channel
Morphological data for the as-built profile was collected in March and April 2020. Refer to Appendix 2
for stream photographs and Appendix 4 for summary data tables and morphological plots.
Profile
The MY0 longitudinal profiles closely match the design profile on Catfish Creek Reach 4 and UT1 Reach
2. Bedrock within the floodplain resulted in a section of Catfish Creek Reach 6 to be realigned and some
adjustments to be made on UT1 Reach 3 but the overall slope is consistent with design. The bedrock
would not allow for as many pools as were designed, this resulted in a predominantly riffle section on
Catfish Creek Reach 6. On the design profiles, pools and riffles were depicted as straight lines with

Catfish Pond Mitigation Site
Baseline Monitoring Document and As-Built Baseline Report-FINAL 5-2
consistent slopes. The as-built surveyed profiles are not as consistent in slope due to natural deposition,
scour, and bedrock. Pool and riffle depths and slopes are expected to be maintained near design
parameter values. The variations in slope and depth do not constitute a problem or indicate a need for
remedial actions and will be assessed visually during site walks.
Dimension
The MY0 channel dimensions are within an acceptable range of the design parameters. The channels are
expected to maintain dimensions of C4 or B4a Rosgen type channels. Summary data and cross-section
plots of each project reach are included in Appendix 4.
Pattern
The MY0 pattern metrics fall within an acceptable range of the design parameters. No major changes to
design alignments were made during construction on Catfish Creek Reach 4 and UT1 Reach 2 and 3.
Catfish Creek Reach 6 had to be re-aligned between station 119+81 and 121+90 due to bedrock in the
floodplain. Pattern data will be evaluated in monitoring year five if channel dimensions or profile
indicate that significant geomorphic changes have occurred.
Sediment Transport
As-built shear stresses and velocities are similar to design calculations and should reduce the risk of
further erosion along the reaches. The as-built condition for each of these reaches indicates an overall
increase in substrate particle size (Appendix 4). The shear stresses calculated for the constructed
channels are within the allowable range, which indicates the channel is not at risk to trend toward
channel degradation.
5.2.2 Hydrology
Bankfull events recorded following completion of construction will be reported in the MY1 report.
5.2.3 Wetlands
Wetland data recorded following completion of construction will be reported in the MY1 report for
informational purposes only.
5.2.4 Vegetation
The MY0 vegetation survey was completed in April 2020. The MY0 planted density is 553 stems per acre
which exceeds the MY3 interim stem density requirement of 320 planted stems per acre. Vegetation
plot photographs are included in Appendix 2 and summary data for each plot are included in Tables 6a
and 6b in Appendix 3.

Take exit 279B for NC-147 N towards Durham/Downtown.
Travel approximately 8 miles and exit onto Duke Street.
Merge onto South Duke Street and continue 4.3 miles until
South Duke Street merges with US-501 N/N Roxboro Street.
Travel north on US-501 N/N Roxboro Street for 7.5 miles.
Make a U-turn and travel south on N Roxboro Street for 0.2
miles, turn right on the first gravel road. Drive approximately
0.2 miles and take the first right onto another gravel road.
The Site is located at the end of the gravel road.
The subject project site is an environmental restoration site of the
NCDEQ Division of Mitigation Services (DMS) and is
encompassed by a recorded conservation easement, but is
bordered by land under private ownership. Accessing the site may
require traversing areas near or along the easement boundary and
therefore access by the general public is not permitted. Access by
authorized personnel of state and federal agencies or their
designees/contractors involved in the development, oversight,
and stewardship of the restoration site is permitted within the terms
and timeframes of their defined roles. Any intended site visitation or
activity by any person outside of these previously sanctioned roles
and activites requires prior coordination with DMS.

Catfish Pond Mitigation Site Buffer Baseline Monitoring Report
DMS ID No. 100039 Page 1 July 2020
1.0 Mitigation Project Summary
The Catfish Pond Buffer Mitigation Site (Site) is a riparian restoration project located in Durham County
approximately 12 miles north of the City of Durham and approximately 3 miles east of the Orange
County/Durham County border (Figure 1). Figure 2 depicts the service area of the Site which includes
the Falls Lake watershed in the Neuse river basin. A conservation easement comprised of 20.73 acres
along Catfish Creek and three unnamed tributaries was recorded on the Site (Figure 3). Before
construction, the majority of the Site was used as cattle pasture, with some forested riparian areas. In
addition, Catfish Pond was a significant source of degradation on Catfish Creek. The project is expected
to generate 523,358.865 riparian buffer credits.
The Site is within Hydrologic Unit Code (HUC) 03020201020040 and North Carolina Department of
Water Resources (NCDWR) Sub-basin 03-04-01. Two unnamed tributaries (UT1 and UT2) drain to Catfish
Creek, which drains to Mountain Creek, and one unnamed tributary (Mountain Tributary) drains directly
to Mountain Creek. Mountain Creek flows into Little River, the Eno River, and then Falls Lake. Falls Lake
is classified as water supply waters (WS-IV) and nutrient sensitive waters (NSW).
1.1 Project Goals
The major goals of the riparian restoration project are to provide ecological and water quality
enhancements to the Neuse River Watershed within the Falls Lake Water Supply Watershed by creating
a functional riparian corridor and restoring the riparian area. The project supports specific goals
identified in the 2010 Neuse River Basin Restoration Priorities Plan (RBRP) for the Neuse River Targeted
Local Watershed (TLW). This document highlights the importance of riparian buffers for stream
restoration projects. Forested riparian areas immobilize and retain nutrients and suspended sediment.
The RBRP also supports the Falls Lake watershed plan. Falls Lake is the receiving water supply water
body downstream of the Site and is classified as WS-IV and NSW. Specific enhancements to water
quality and ecological processes are outlined below:
• Exclude cattle from project streams – Fencing has been installed around project areas adjacent
to cattle pastures.
• Decrease nutrient levels – Filtering runoff from the agricultural fields through restored native
riparian zones. The off-site nutrient input is absorbed on-site by filtering flood flows through
restored floodplain areas, where flood flows can disperse through native vegetation.
• Decrease water temperature and increase dissolved oxygen concentrations – Riparian areas will
create additional long-term shading of the channel flow to reduce thermal pollution.
• Restore and enhance native floodplain vegetation – Planted native tree species in riparian zone
where tree growth was insufficient.
• Permanently protect the project Site from harmful uses – Established a conservation easement
on the site.
1.2 Pre-construction Site Conditions
The riparian restoration project includes 20.73 acres of cattle pasture and riparian forest along Catfish
Creek and the three unnamed tributaries that drain into the Neuse River Basin. Prior to construction, the
primary degradation of Catfish Creek was the creation of Catfish Pond sometime between 1940 and
1955. In that same time period extensive logging and farm road construction also took place. Aerial
photographs from 1972 suggest that UT1 had been straightened for agricultural purposes. Catfish Creek
above and below the pond, UT2, and Mountain Tributary showed few signs of channel manipulation.

Catfish Pond Mitigation Site Buffer Baseline Monitoring Report
DMS ID No. 100039 Page 2 July 2020
Two unnamed tributaries (UT1 and UT2) drain to Catfish Creek, which drains to Mountain Creek, and
one unnamed tributary (Mountain Tributary) drains directly to Mountain Creek. Catfish Creek, UT1, UT2,
and Mountain Tributary are all jurisdictional streams. The buffer project attributes are listed in Table 1,
located in Appendix 1.
On May 13, 2018, NCDWR conducted on-site determinations to review features and land use within the
project boundary. The resulting NCDWR site viability letter and map confirming the Site as suitable for
riparian buffer and nutrient offset mitigation is located in Appendix 2. Catfish Creek and the three
unnamed tributaries are appropriate for buffer and nutrient offset mitigation as related to the rules set
forth in the Neuse Buffer Mitigation Rules: Mitigation Program Requirements for Protection and
Maintenance of Riparian Buffers (15A NCAC 02B .0295) and Neuse River Basin: Nutrient Sensitive
Waters Management Strategy: Protection and Maintenance of Existing Riparian Buffers (15A NCAC 02B
.0233).
2.0 Determination of Credits
The project is expected to generate 523,358.865 riparian buffer credits, through buffer restoration and
buffer enhancement via cattle exclusion, per the Consolidated Buffer Mitigation Rules (15A NCAC 02B
0.0295 (o)). There is also potential to convert some buffer credits to nutrient offset credits, dependent
on the need. Mitigation credits are presented in Table 2 and illustrated in Figure 3 (Appendix 1).
Calculations are based upon the as-built survey included in Appendix 3.
In the Mitigation Plan, 0.1 acres of buffer restoration credits were removed around Ditch D because it
did not meet the requirement to maintain diffuse flow throughout the buffer. With the addition of
Catfish Pond II Mitigation Bank Parcel (DWR Project Number 2018-0196v2), this deduction is no longer
necessary. The Catfish Pond II conservation easement completely encompasses Ditch D allowing for
diffuse flow. Fencing has been installed around Catfish Pond II (Appendix 1, Figure 4).
3.0 Baseline Summary
The Wildlands Team restored high quality riparian areas along Catfish Creek and three unnamed
tributaries on the Site. The buffer and nutrient offset mitigation took place in conjunction with Catfish
Pond Stream Mitigation. The project design ensured that no adverse impacts to existing riparian areas
occurred. Figure 3 illustrates the conceptual design for the Site. Detailed descriptions of the restoration
activity follow in Sections 3.1 through 3.4. Overview site photographs are included in Appendix 4.
3.1 Parcel Preparation
Prior to stream construction, the Site was cattle pasture, with livestock having access to all streams
causing streambank erosion. UT1 was also channelized to maximize land use. Catfish Pond was removed
during stream construction and the four streams were restored and/or enhanced. The approved permits
are included in Appendix 5. During stream construction, invasive plants were targeted and removed to
reduce native competition. Soil amendments were added to certain graded areas after construction as
directed by soil test results. Amendments included agricultural lime, slow release fertilizer, and soil
conditioners (humic acid, organic material, soil biota stimulants). Haul roads and other high trafficked
areas were also ripped to a depth of 18” where possible to reduce soil compaction.
3.2 Riparian Area Restoration Activities
The revegetation plan for the riparian restoration area included permanent seeding and planting bare
root trees. These revegetation efforts were coupled with the select treatment of invasive species to
control their population. The species composition planted was selected based on the desired community

Catfish Pond Mitigation Site Buffer Baseline Monitoring Report
DMS ID No. 100039 Page 3 July 2020
type, occurrence of species in riparian areas adjacent to the Site, and best professional judgement. The
total number of tree species planted across the buffer areas are as follows: sycamore (Platanus
occidentalis) 1,207 stems, river birch (Betula nigra) 927 stems, green ash (Fraxinus pennsylvanica) 646
stems, Shumard oak (Quercus shumardii) 646 stems, swamp chestnut oak (Quercus michauxii) 646
stems, willow oak (Quercus phellos) 646 stems, white oak (Quercus alba) 365 stems, overcup oak
(Quercus lyrata) 365 stems, and 55 stems each of arrowwood viburnum (Viburnum dentatum), smooth
serviceberry (Amelanchier laevis), and yellow buckeye (Aesculus flava). Additionally, 350 stems each of
silky dogwood (Cornus ammomum) and silky willow (Salix sericea) and 100 stems of elderberry
(Sambucus canadensis) were planted along streambanks. In total, 6,413 stems were planted across the
site.
Trees were planted at a density sufficient to meet the performance standards outlined in the Rule 15A
NCAC 02B .0295 of 260 trees per acre at the end of five years. An appropriate seed mix was applied as
necessary to provide temporary ground cover for soil stabilization and reduction of sediment loss during
rain events in disturbed areas. This was followed by an appropriate permanent seed mixture. Tree
planting was completed in March 2020.
Vegetation management and herbicide applications are being implemented as needed during tree
establishment in the restoration areas to prevent establishment of invasive species that could compete
with the planted native species.
3.3 Riparian Area Enhancement Activities
Fencing was used to exclude cattle throughout the entire project as allowed by 15A NCAC 02B .0295(o)
and minimal work was done on the streams through the enhancement areas. Fencing was built to
incorporate the conservation easement for Catfish Pond II Mitigation Bank Parcel as shown in Figure 4.
The enhancement area has been protected in perpetuity under a conservation easement.
4.0 Annual Monitoring and Performance Criteria
The performance criteria for the Site follows approved performance criteria presented in the guidance
documents outlined in Request for Proposal (RFP) 16-007279 and the Consolidated Buffer Rule (15A
NCAC 02B .0295). Annual monitoring and semi-annual site visits will be conducted to assess the
condition of the finished project. The riparian restoration project has been assigned specific
performance criteria components for vegetation that will be evaluated throughout the five-year post-
construction monitoring. An outline of the performance criteria and monitoring components follows.
Monitoring components are included in Table 3 and vegetation plots are depicted in Figure 5 (Appendix
1).
4.1 Vegetation
Performance Standards for the Site will be based on the health and survival of a minimum density of 260
trees per acre after five years of monitoring, with a minimum of four native hardwood tree or shrub
species composition and no one species comprising more than 50 percent of stems. Height, visual
assessment of damage, and vigor will be used as indicators of overall health. Desirable volunteer species
may be included to meet the success criteria upon DWR approval. The extent of invasive species
coverage will also be monitored and treated as necessary throughout the required five-year monitoring
period.
Seven fixed 100 square meter vegetation monitoring quadrants were installed across the Site to
measure the survival of the planted stems (Figure 5) with a mean of 561 stems per acre (Table 4).
Vegetation monitoring follows the CVS-EEP Level 2 Protocol for Recording Vegetation (2008). All planted
stems were marked with flagging tape and a reference photograph was taken from the southwestern

Catfish Pond Mitigation Site Buffer Baseline Monitoring Report
DMS ID No. 100039 Page 4 July 2020
corner of each vegetation plot during vegetation assessments. Each year, trees will be re-marked and
plot photos will be taken along with overview photographs of the Site. Appendix 6 includes the baseline
(MY0) vegetation plot planted and total stem counts, as well as plot photographs.
4.2 Overview Photographs
Photographs will be taken within the project area once a year to visually document stability for five
years following construction. Baseline overview photographs are included in Appendix 4.
4.3 Visual Assessments
Visual assessments should support the performance standards for each metric as described above.
Visual assessments will be performed within the Site on a semi-annual basis during the five-year
monitoring period. Problem areas with vegetative health will be noted (e.g. low stem density, vegetation
mortality, invasive species, or encroachment). Areas of concern will be mapped and photographed
accompanied by a written description in the annual report. Problem areas will be re-evaluated during
each subsequent visual assessment.
4.4 Annual Reporting Performance Criteria
Using the Division of Mitigation Services (DMS) Riparian Buffer and Nutrient Offset Buffer Baseline and
Annual Monitoring Report Template version 2.0 (2017), monitoring reports will be prepared in the fall of
each monitoring year and submitted to DMS. The monitoring period will extend five years beyond
completion of construction or until performance criteria have been met.
4.5 Maintenance and Contingency Plans
The conservation easement has been properly and accurately marked by adding witness posts with
easement placards along the easement boundary and at every corner. Adaptive management will be
performed during the monitoring years to address minor issues as necessary. If during annual
monitoring it is determined the project’s ability to achieve performance standards are jeopardized,
Wildlands will notify and work with the DMS/NCDWR to develop contingency plans and remedial
actions. Any actions implemented will be designed to achieve the success criteria specified previously
and will include a work schedule and updated monitoring criteria (if applicable).

Dear Mr. Hutton,
On February 23, 2018, Katie Merritt, with the Division of Water Resources (DWR), assisted you
and others from Wildlands Engineering, Inc. at the proposed Catfish Pond Mitigation Site (Site)
in Bahama, NC. The Site is located in the Falls Lake WS of the Neuse River Basin within the 8-
digit Hydrologic Unit Code 03020201. The Site is being proposed as part of a full-delivery
stream restoration project for the Division of Mitigation Services (RFP #16-007279). Members
of the Interagency Review Team (IRT) and Division of Mitigation Services were also present
onsite. At your request, on February 23, 2018, Ms. Merritt performed an onsite assessment of
riparian land uses adjacent to streams and ditches onsite, which are shown on the attached map
labeled "Figure 6A Concept Map".
Ms. Merritt's evaluation of the features onsite and their associated mitigation determination for the
riparian areas are provided in the table below. This evaluation was made from Top of Bank (TOB)
out to 200' from each feature for buffer mitigation pursuant to 15A NCAC 02B .0295 ( effective
November 1, 2015) and for nutrient offset credits pursuant to 15A NCAC 02B .0240.

March 13, 2018
The attached map (Figure GA Concept Map) showing the project site and features was provided by
Wildlands Engineering and was initialed by Ms. Merritt on March 13, 2018. There were at least 3
crossings that need to he repaired or replaced to allow for aquatic passage and continuous
hydrologic connectively throughout the streams. This letter should be provided in any future
stream, wetland, buffer and/or nutrient offset mitigation plans for this Site.
This letter does not constitute an approval of this site to generate mitigation credits. Pursuant to 15A
NCAC 02B .0295, a mitigation proposal and a mitigation plan shall be submitted to DWR for written
approval prior to conducting any mitigation activities in riparian areas and/or surface waters for
buffer mitigation credit. Pursuant to 15A NCAC 02B .0240, a proposal regarding a proposed nutrient
load -reducing measure for nutrient offset credit shall be submitted to DWR. for approval prior to any
mitigation activities in riparian areas and/or surface waters.
All vegetative plantings, performance criteria and other mitigation requirements for riparian
restoration, enhancement and preservation must follow the requirements in 15A NCAC 02B .0295 to
be eligible for buffer and/or nutrient offset mitigation credits. For any areas depicted as not being
viable for nutrient offset credit above, one could propose a different measure, along with supporting
calculations and sufficient detail to support estimates of load reduction, for review by the DWR to
determine viability for nutrient offset in accordance with 15A NCAC 02B .0240. For any areas
generating wetland mitigation credit, no buffer or nutrient offset credit can be generated.
This viability assessment will expire on March 13, 2020 or upon the submittal of an As -Built
Report to the DWR, whichever comes first. Please contact Katie Merritt at (919)-807-5371 if you
have any questions regarding this correspondence.
